So does it mean that people from a Chinese background celebrating St Patrick and dressing in green would be culturally insensitive because that's not their culture ? Or are white people practicing judo and wearing a kimono racist toward Japanese people ? Or that a latino female cannot teach yoga because it's cultural appropriation and disrespectful toward Indians ? So did that college ban all these stuff already because PC ? where does it stop ? everybody sticks to their culture and we enable global separation by race, sex, gender, country of origin in College so nobody get outraged at something somebody different than him might do ?
